MAHR MaraMeter Self Centering Dial Bore Gage 844 N Sets
Indicator in photo sold separately
Application:
- Measuring the diameter, roundness and conical form of a bore as well as the distances of plane parallel surfaces
Features:
- Measuring head consists of a carbide tipped moving anvil and an interchangeable stationary anvil with a hardened steel ball
- Transmission lever system transfers movement of the movable anvil to indicating instrument
- The broad centering bridge ensures automatic centering in the bore
- Resistant to temperature because the shank and transfer rod are made of heat resistant Invar steel
- Highly resistant to wear and tear because of carbide tipped moving anvil
- Constant measuring force due to built-in spring, eliminating user influence
- Universally applicable and extremely versatile as every instrument spans a broad measuring range, within this range it is quick and easy to adjust to any size
- Extensive modular system is composed of measuring head, holder, extensions, right angle attachments and depth stops
- Invar steel has a particularly low expansion coefficient and thus makes the instrument totally insensitive to any kind of heat. Body heat from the user, increases in ambient temperature have no influence on the measuring results
